Hirnwelt oder Lebenswelt? Zur Kritik des Neurokonstruktivismus

Abstract From a neuroconstructivistic point of view, the human brain produces an internal simulation of the external world which appears in conscious experience as the phenomenal world. This concept implies in particular that the subjective body and the organic or objective body belong to fundamentally different realms, i.e. to the mental and the physical world. The spatiality of the subject-body has then to be declared an illusion, which is done by pointing to dissociations of the subject- and object-body as in the rubber hand illusion or in phantom limbs. This alleged virtuality of body experience may be refuted, however, namely by referring to the intersubjectivity of perception which certifies the coextensivity of subject-body and object-body. Subjectivity is thus shown to be embodied as well as spatially extended, that means, as bodily being-in-the-world.
